This has nothing to do with Medicare. The G5 receiver is only available in black, no matter what insurance you have. My guess would be that because the G5 is centered around smartphone usage, Dexcom didn’t think it would be a wise financial decision to offer the receiver in different colors, like they did with the G4. With the advent of smartphone usage as the receiver, most of their patients will be using their smartphone and ditch the receiver. Having a bunch of different color receivers laying around on their shelves is not what Dexcom wants.
